FEATURES
● Operating voltage range: – VCC range: 2.7V to 5.5V – Logic pins compatible with 1.8V, 3.3V, and 5V● 4 constant current sinks with high precision: – 0.1mA to 51mA per current sink – Device-to-device error: max ±5% – Channel-to-channel error: max ±5% – Ultra-low headroom voltage: 110mV (typ.) at 25.5mA; 210mV (typ.) at 51mA – PWM phase shift configurable for each LED
● Ultra-low power consumption: – Standby: ISTB = 26μA (typical) when CHIP_EN = 0 (data retained) – Active: INOR = 0.4mA (typical) when LED current = 25.5mA
● Analog dimming (current gain control) – Global 1-bit Maximum Current (MC): 25.5mA or 51mA – Individual 8-bit Dot Current (DC) setting
● PWM dimming up to audible-noise-free 24kHz – Individual 8-bit PWM dimming resolution – Linear or exponential dimming curves
● Autonomous animation engine control
